tab between full page midi event editor

when you expand the lower midi edit zone into full page, have the option being able to ‘tab’ to the next midi part without having to switch windows back into the arranger to click on the next midi part on the track and then switch windows back in to the midi editor again.

This is similar to the heavily requested tabs feature for unifying opened VST3 windows which i believe has been implemented already in waves labs i think?
